SPECIFICATION forming part of Letters Patent No. 688,683, dated December10, 1901. Application filed February 23, 1899. Serial No. 706,456. (Nomodelil.

To all whom it may concern.-

Be itknown that I, GEORGE W. PHILLIPS, a citizen of the United States,residing at Camden, in the county of Camden and State of New Jersey,have invented a certain new and useful Improvement in Devices forStopping Leakage, of which the following is a specification.

My invention relates to a new and useful improvement in devices forstopping leakage at pipe-couplings and upon valve-stems and the likewithout in any Wise interfering with the pipe-coupling or stem, thusavoiding the necessity to shut down or turn off the steam, in case aleakage occurs, to repack or adjust the joint.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinafterset forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which--Figure 1 represents a pipe and coupling, showing my improvement appliedthereto for stopping the leakage; Fig. 2, a longitudinal sectionthereof, and Fig. 3 a cross-section.

In carrying out my invention as here embodied I provide acontaining-ring A, which is made in two sections adapted to be securedtogether by bolts, as indicated at B, the object being to permit itsbeing placed around a pipe 0 without disturbing the couplings, and whenso placed and bolted together the packing D is placed therein in suchmanner as to abut against the face of the coupling E, as clearly shownin Fig. 2. F is likewise a sectional ring bolted together, as indicatedat G, but of a diameter which more snugly fits the pipe 0, but notintended to bind thereon. This ring has formed therewith an offset II,after the manner of a stufling-box gland, and is adapted to pass'wit-hinthe containing-ring A, and thus bear against the packing D. I representsthe adjusting-ring, which is-also made in two sections and boltedtogether, as indicated at J, and this ring is intended to be clampedtightly against the pipe 0, so as to have no movement thereon. For thispurpose the set-bolts K are threaded through the ring, their inner endsadapted to bear firmly against the pipe. 'When these three rings are inposition, any leakage between the pipe 0 and coupling E is stopped bythe setting up of the adj Listing-bolts L, which are threaded throughthe ring I and bear against the face of the ring F. The adjustment ofthese bolts, as is obvious, will force the packing D against the face ofthe coupling E and also by reason of the shape of the inner surface ofthe offset H cause said packing to be forced inward against the pipe 0,thereby completely shutting oif any leakage which may be taking place atthis point.

By the use of a number of the adjustingbolts L the setting up of thepacking is made easy, since the strain is distributed upon all of theseadjusting-bolts and which may be manipulated by a short wrench, afurther advantage being that more or less pressure may be brought uponany portion of the packing by the proper manipulation of the adj usting-bolts.

One of the principal advantages of my improvement is that no sidewise oraxial strain is brought to bear upon the coupling or pipe, and thereforethe relation between these two members is not disturbed by the use ofmyimprovement.

While I have shown my improvement adapted for use in connection with apipe or a coupling, it is obvious that when made of proper size it maylikewise be adapted for use upon valve-stems and the like for stoppingleakage thereon without the necessity of shutting down to pack saidvalves.

Another advantage of my improvement is its exceeding simplicity and thesmall cost attendant upon its manufacture, the several parts beingcapable of being cast of malleable iron and requiring no finish, as theyare not required to accurately fit the pipe or the coupling.

Having thus fully described my invention, What I claim as new and usefulis- 1. Devices for stopping leakage, consisting of a containing-ringmade in sections adapted to receive suitable packing, a gland-ring alsomade in sections adapted to bear against said packing, an adjusting-ringadapted to be made stationary, and'adj usti ng-scre ws passed throughthe last-named ring for setting up the gland-ring, as specified.

2. In combination, a containing-ring made of two sections and adapted tobe bolted around a pipe orthe like and receive suitable packing, agland-ring also made in two sections and adapted to be bolted around thepipe, an adjusting-ring likewise made in two sections and adapted tobe'bolted in contact with the pipe, set-screws threaded through saidring for holding it in position upon the pipe, and adjusting-boltsthreaded through the last-named ring and adapted to force the gland-ringagainst the packing whereby the latter is compressed against thecoupling and pipe to stop the leakage, as specified.

3. In a pipe-clamp, the combination with a removable annulus adapted tobe fixedly supported upon a pipe, of a packing-strip movablelongitudinally of the annulus and adapted for fixed engagement with anopposed face of a pipe-joint, and a plurality of independently-actingadjusting devices acting longitudinally ot' the pipe for eiiecting afixed engagement. between the packing-strip and an opposed face of apipe-joint; v

4. In a pipe-clamp, the combination with an annulus adapted to befixedly supported upon a pipe, of an annular packin -strip, a ringencircling the packing-strip, and a plurality of independently-actingadjusting devices acting longitudinally of the pipe for effecting afixed engagement between the packing-strip and an opposite face of thepipejoint.

5. The combination with an annulus formed in sections, of means forsecuring said annulus about a pipe, a second annulus formed in sectionsand having a packing-face, and longitudinally-acting screws carried bythe firstaforesaid annulus, adapted for engagement with the latterannulus to force the same longitudinally of the pipe and thereby effectfixed engagement between the packing-face and the pipe-joint.

v 6. The combination with an annulus formed in sections, of a pluralityof radially-acting screws for fixing said annulus about a pipe, a secondannulus formed in sections and having a packing-face, andlongitudinally-acting screws carried by the first-aforesaid annulus,adapted for engagement with the latter annulus to force the samelongitudinally of the pipe and thereby efiect fixed engagement betweenthe packing-face and the pipe-joint.

7. A detachable containing-ring to receive the packing, an annularpacking within said ring, a detachable adjusting-ring adapted to besecured against movement upon the pipe, an annular gland-ring to bearagainst said packing, and a series of adjusting-screws as set forth. 7

8. A detachable containing-ring to receive the packing, an annularpacking within said ring, a detachable adjusting-ring adapted to besecured against movement upon the pipe, an annular gland-ring to bearagainst said packing and a plurality of forcing devices acting upon thegland-ring to compress the packing.

9. A detachable containing-ring to receive the packing, an annularpacking within said ring, a detachable adjusting-ring adapted to besecured against movement upon the pipe, an annular gland-ring to bearagainst said packing, anda series of adjusting-screws threaded throughthe adj usting-ring and bearing upon the gland-ring, as set forth.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.
